Lean PlanDo manual › Lookahead
Edit a task dependency
Change the type or lag of a task dependency, disable it or delete it, so the Lookahead matches the planned construction sequence.
You can edit a task dependency at any time. Change the type and lag of an existing dependency, or disable or delete the whole dependency, to match the planned construction sequence.
A task's dependencies are listed in its Dependency list tab. Lag is the number of days added between a predecessor and its successor.
Edit a dependency
- Double-click the task bar in the Gantt chart.
- Click Dependency list.
- Click Edit (pencil icon) beside the predecessor or successor task you want to change.
- Make the changes, then click Save to update the dependency.

Delete a dependency
- Click Delete (bin icon) beside the dependency.
You cannot edit or delete a dependency whose successor task is committed. Deleting also needs permission to delete task dependencies.
Enable or disable a dependency
Each dependency has an on/off switch at its left. It is on by default. Turn it off to disable the dependency.
Activity dependencies are edited the same way. See Edit an activity dependency.
